Cannabinoids affect positive and negative affective experience and emotional perception, possibly by modulating limbic brain reactivity. In this double-blind crossover, placebo-controlled functional magnetic resonance imaging study in humans, an acute oral dose of ∆(9)-tetrahydrocannabinol (THC) attenuated subgenual anterior cingulate cortex (sgACC) reactivity during the induction of negative affect. This observation extends prior findings implicating a cortico-limbic, emotion-related central mechanism underlying cannabinoid function.
大麻素影响积极和消极的情感体验和情绪感知,可能通过调节边缘脑反应来实现。在这项人类双盲交叉安慰剂对照功能磁共振成像研究中,急性口服 ∆(9)-四氢大麻酚 (THC) 可减弱诱导负性情绪时的扣带前回下部 (sgACC) 反应。这一观察结果扩展了先前的发现,表明大麻素功能的核心机制涉及皮质-边缘,与情绪相关的中枢机制。
